material as peat or the like' where-it is 'de-;

sirable to convey same some considerable distauceat theleast expensefpossible.

Peat is' 'fr'equently found in low l ing tracts of land in semi or wholly, submerged and marsh like condition where [it 'bec'oines convenient for associating water therewith for various purposes, orv water may be-made available for utilization of my present invention where-the peat to be had is in dry and more granular or mass conditions;

The principal object of my present inven---' tion is the providing oii. means for more thoroughly preparing the-peat for such form and method of transportation.

vention will appear in the further description thereof. 7 Referring to the accompanying drawing formingpart of this application in which like reference characters indicate like parts: Figure 1 is a vertical central sectional View through one of the devices embodying my invention, v

Figure 2 is a top .plan view'of one of the complete devices,and, V V

V In carrying out the. invention," I prefer to employ a long narrow anddeep trough l of any preferred construction and through which a mixture of water and peat may be conveyed, for which purpose I prefer to shave the trough inclined slightly downwardly towards the discharge end thereof.

At the upper end of the trough is provided a hopper like receiver 2 extending upwardly therefrom beneath which and within the trough are two horizontally spaced crushing or disintegrating rollers 3, they being provided with suitable spiked teeth 'veyor,'and the water alone provided through V 'the lower dischargeend, allowing theclearer Other'obj'ects and advantages of the in- 4 ,proaches the lo'werendof the trough. r This termination'of the-trough-i's provided or corrugations, or a combinationof both,-

for crushing.and.disin'tegrating the peat as dis discharged onto them through thehopper. These rollers may be givenrotati-ve' motion from anysource 05f powerdesired, is obvlous, forthe'ipurpose intended; V .1

.l?eat and water are' 'discharged into; the

hopper eitherby means or afsuitable' pipe i and dipper-or other 'loucketoyor, ifthef conditions are convenient "for;sucl1, :the supply; of peat and w'ater may {'behwholly provided by an hydraulic apparatus: or

w ill become thoroughly disintegrated and it crushed by thea'ction oftherollers: as .Well"'Z 7' it will beaconveyed thereby longitu din'all'yx 1 and downwardly of the trough. In'practice 2 it is intended toprovide sutficient water to keep the trough practically filled at all times so that in its traversing the trough the peat will gradually settle towards the bottom thereof and becomelthicker as it approaches water to remainc-neara-the" surface as "it ap with a closed end 6 through whichlextends the rece ving end 7fof the conveying.- pipe line which maybe so located as to conduct the mixture thus provided by gravity to the place of deposit desired. {One or more cen trlfugal pumps 8 may be'installedwithin the pipeline 'atany placeconvenient to provide l the necessary power for conveying the peat and water in the pipe, if gravityis not suiiia T cient for such purpose,- 'andfsuch-1 umps i J or continuation or" the pi pump being shown at 10; J

Adjacent. the" upperiedge' of the trough H and near the lowermost endthereof I have provideda number (it-holes or openings 11 0 7 through which the clear water in the trough j may overflow and be conveyed in a suitable I trench upon the ground beneath the trough "i or otherwise back-t0 the-placeof original water supply which is furnished to thef t' It is evident from the above that the supply and, discharge from the trough maybe easily re ulated to result in the desired sep-' aration of the Water and material in the trough, and the proper proportion thereof which, may be admitted to the conveying pipe line, so'that the largest proportion possible of peat may be conveyed through said pipe With the least aino int of Water and it being thoroughly disintegrated or pulverr ized and mixed Witli'the Water will provide 'Patent, is: r

against any possible clogging-or stoppage in: the pipe so long as'the ater is kept in motion therein. 7

Inthis manner great quantities of such light granular material may beconveniently conveyed, and theuse-of such a device results in the inostjeconomical form of transporting pe a A Having 'thus described my invention, what I claim and desireto secure by Letters 1 A device for thefpreparationof gran- .ular: material for hydraulic transportation thereof for receiving the heavier and thicker contents or" the trough, and discharge openings adjacent the upper edge of the trough for the discharge of separated Water from Where it maybe returned for subse quent use.

2. A device for the preparation of gran -ular material for hydraullc' transportation comprising anf elongated inclined trough,

mixing and disintegrating means 'Within'the upper end of the trough, a Water and material suo l to the mixin and disinte rat-, i

ing means, a discharge opening at the lower end of the trough and adjacent the bottomf thereof for removing only the thicker-ma terial therefrom, and aplurality of spaced overflow openings along the 1 upper edges of the trough for the purpose described. I

In testimony whereof I hereuntov aflixmy signature in the presenceotone Witness.
